tohatsu 3.5 2stroke ob cover removal ?

Hehe,

I don't mind the abuse, some of us think before removing a bunch of screws out of an OB that's hanging off the back of a boat ;)

'Just going to show how memory fails in the aged - looked @ mine and it's on the starboard - with a little hole in the cowling to allow tactical interference'

Tnx, that's what the guy who supplied the OB said too.

Additionally the OB may run fast on a rich mixture, which it has, no comment :)

If its any help I always try to do it in the bottom of the dinghy. Fiberglass with no frames and no spaces for screws to run to, so its hard to drop anything over the side. If you so it in the cockpit remember the scuppers!

If you really must work on an outboard on the transom I have found that hanging a large bucket underneath the powerhead can catch the bits that drop off. One of those big gorilla soft buckets that builders use is a good bet.

But a small Tohatsu lifts off very easily.

Just taken the carb apart to give it a clean as the engine was only running with some choke applied, could somebody confirm where the needle goes back into so I don't make a silly mistake?

I take it you mean the main jet needle. Down through the middle of the throttle valve piston

Useful exploded diagrams on the Tohatsu parts website http://www.tohatsuoutboardparts.com/Parts-Books.html

Quicker downloads maybe from http://www.boats.net/parts/search/Tohatsu/Outboard/parts.html

Lots more detailed info and instructions for similar carb in the manual on Lakesailors site http://www.lakelandimages.co.uk/Forum pics/info_engine/Tohatsu/

Make sure you fit the clip on the needle in its original position.

Make sure the main jet and nozzle are completely clear.

Many thanks for that.

It's called the needle valve (part number 1-19, page 15) according to the part book.

Oh that is the needle that controls the fuel entry

It just slips into place, AFAICS, pointed end up.

It is only retained by the "float hinge" arm. Watch out that it does not fall out again.

Some modern needles have a soft tip and a tiny wee clip between them and the float arm . If that is the case be sure that the clip is fitted correctly or the needle may tend to stick on its seat.
